Public inputs (#113)
With this approach, we don't need `Target::PublicInput`; any routable `Target` can be marked as a public input via `register_public_input`.  The circuit itself hashes these targets, and routes the hash output to the first four wires of a `PublicInputGate`, which is placed at an arbitrary location in the circuit.

All gates have direct access to the purported hash of public inputs. We could think of them as accessing `PI_hash_i(x)` (as in Plonk), but these are now (four) constant functions, so they effectively have direct access to the hash itself.

`PublicInputGate` checks that its first four wires match this purported public input hash. The other gates ignore the hash.

Resolves #64.
